The concepts of Physical Geography are explained in an uncomplicated manner and can be understood by anyone. These national textbooks are prepared after much research and by experts, hence you can be certain of their quality.
The one I read was for class 11. It was an awful read and was extremely dry. I think Geography will continue to remain dry unless an explicit effort is made to link it with people, history, philosophy as a part of the larger connected world we all live in.
